Sleep Condition Indicator
The Sleep Condition Indicator is a brief insomnia-oriented self-report. This page is for clinics. It is not a stand-alone insomnia diagnosis and not a public test.
Overview
What is the SCI?
The SCI organises insomnia-related complaints for clinician review. It is not interchangeable with ISI or AIS, and it is not a sleep-disorder diagnosis.
Development and clinical use
Espie and colleagues published the SCI in 2014 as a brief screening tool that appraises insomnia symptoms against DSM-5 criteria.

Administration
A focused client experience
Respondents answer eight questions about a typical night in the last month, how poor sleep has affected them over the past month, and how long they have had a sleep problem. Each answer scores from 4 (best sleep) to 0.
- One question at a time with visible progress
- Large keyboard-operable response choices
- Previous, next, and answer-review steps
- Clear confirmation that results go to the clinic

Designed to make evidence easy to review
The downloadable synthetic example illustrates report layout using invented response patterns, without patient data or instrument questions.

- Responsible clinician review rather than automated conclusions
Clinician review required
Methodology
Understand the measure and its scoring conventions
Published scoring adds the eight items for a total from 0 to 32, where a higher score means better sleep. Espie and colleagues report that a score of 16 or lower may help detect probable insomnia disorder. This public page does not independently verify scoring, cutoffs, or a production scoring rule.

Questions
What clinics ask before they evaluate the SCI
These answers stay inside educational catalogue scope. They do not replace official manuals or clinician judgement.
Does SCI replace a sleep assessment?
No. It is a self-report screen. Diagnosis and investigation remain clinician tasks.
Can I complete SCI here?
No. This landing is educational catalogue information.
How is SCI used on Lirena?
As a sleep-intake self-report. Clinicians review the result with other sleep history.
Is SCI the same as ISI?
No. They are different insomnia-oriented instruments, and their scores run in opposite directions. A higher SCI score means better sleep, while a higher ISI score means more severe insomnia.
